The Thinker is a bronze and marble sculpture by Auguste Rodin, whose first cast, of 1902, is now in the Musée Rodin in Paris; there are some twenty other original castings as well as various other versions, studies, and posthumous castings.

Les Bourgeois de Calais is one of the most famous sculptures by Auguste Rodin, completed in 1889. It serves as a monument to an occurrence in 1347 during the Hundred Years' War, when Calais, an important French port on the English Channel, was under siege by the English for over a year.

The Kiss is an 1889 marble sculpture by the French sculptor Auguste Rodin. Like many of Rodin's best-known individual sculptures, including The Thinker, the embracing couple depicted in the sculpture appeared originally as part of a group of reliefs decorating Rodin's monumental bronze portal The Gates of Hell, commissioned for a planned museum of art in Paris. The couple were later removed from the Gates and replaced with another pair of lovers located on the smaller right-hand column.

The Kiss is a sculpture by Constantin Brâncuşi. It is an example of his abstracted, non-literal representation style. He created many versions of The Kiss, further simplifying forms to geometrical and sparse objects in each version.

Bird in Space (L'Oiseau dans l'espace) is a series of sculptures by Constantin Brâncusi, a Romanian sculptor. The original work was created in 1923. It was sold in 2005 for $27.5 million, a record for a sculpture sold in an auction. The original title in Romanian is "Pasarea în vazduh."
In the Bird in Space works, Brâncusi concentrated not on the physical attributes of the bird but on its movement. The bird's wings and feathers are eliminated, the swell of the body is elongated, and the head and beak are reduced to a slanted oval plane.
